FrankenPfaff breaking thread
I have the most janky quilting rig ever. My new-to-me machine is an old industrial Pfaff 463, but modified for free motion quilting. No feed dogs, and a motor bolted onto the back with a dimmer switch (not kidding) for speed control. We have been calling her Ermingerd, the FrankenPfaff.
Anyway - she makes a seriously beautiful stitch, but I'm trying my first quilt on her, and she keeps breaking thread. After re-threading, correcting upper tension issues (just guessing it's my 3 year old who cranked the dial up to 100 - there's no stop, of course...) and changing needles, I have been able to quilt at very low speed for about a minute before the thread breaks. So now I'm wondering how much of it is the thread. I'm using Robison Anton rayon embroidery thread that's forever old. I'm just guessing I bought it about 12 years ago? (Sheesh. THAT dates me, I think...) Also had some issues winding the bobbin, and it might be too loose on the spindle - not sure if that could be causing trouble as well. But when I pull the bobbin thread it seems to move freely with reasonable "drag".
Any ideas?
